Tether just wrote one of the biggest checks the robotics industry has ever seen, and the plan is to let robots hold their own crypto.

The stablecoin issuer announced it is leading a Series C funding round of up to $1.4B for NEURA Robotics, a German company building humanoid robots powered by AI. The deal, announced on June 10, represents one of the largest private investments in the humanoid robotics sector to date.

Robots with wallets

This isn’t just a financial play. Tether plans to integrate its Wallet Development Kit into NEURA’s robots, giving each machine the ability to maintain a self-custodial crypto wallet. These robots would be able to send, receive, and manage payments on their own, without a human intermediary approving every transaction.

The concept is what Tether calls a “machine economy,” where autonomous systems handle their own financial operations independently.

Nvidia, Amazon, Qualcomm, Bosch, Schaeffler, and the European Investment Bank all participated in the round alongside Tether.

A deal months in the making

Tether’s interest in NEURA dates back to late 2025, when discussions reportedly centered on a roughly $1.16B investment at a valuation between €8B and €10B. By March 2026, reports indicated a potential round at a lower valuation of around €4B. The final Series C terms haven’t been fully detailed, but the up-to-$1.4B figure represents a significant escalation from those earlier conversations.

The funding is designed to support NEURA’s production scaling and its Neuraverse platform, which connects robots, AI models, and computing resources into an integrated system. NEURA has reportedly booked significant orders as global demand for automation and AI technologies continues to surge.

For Tether, this is part of a broader strategic pivot that has seen the company move well beyond its core stablecoin business, deploying capital into AI, data infrastructure, and now robotics.
